| However, some tetraploid lines are facultatively apomictic and an individual plant may set seed both apomictically and sexually. |
|
| In apomictic plants, embryos develop parthenogenetically from unreduced somatic or gametophytic cells. |
|
| In a highly inbred or apomictic group, every individual would be a species according to the biological species concept. |
|
| A major scientific goal in the last decade has been to isolate genes specifically expressed in apomictic genotypes. |
|
| Expression of four oleopollenin genes in eight individuals of the predominantly apomictic species Boechera holboellii. |
|
| However, this seems unlikely since, as far as we know, no apomictic taxa of Primulaceae have been detected. |
|
| This primary function of pollen is a constraint that suffices to explain why apomictic grasses make pollen. |
|
| Maternal apomictic embryos develop from a somatic cell within the ovule or from an unreduced embryo sac derived from the megaspore mother cell. |
|
| It is extremely diverse due to the fact that it is apomictic, i.e. it produces seeds without being fertilized. |
|
| Another type of apomictic development has been reported to occur in the gymnosperm Cupressus dupreziana, where embryos develop from unreduced pollen grains. |
|
| If apomictic seeds are cheap enough, farmers may not think it worthwhile to go to the trouble of saving and storing them. |
|
| Plants that had lost only part of chromosome 16, though, were often still apomictic. |
|
| They are all native to the subtropical and temperate regions of South America, and sexual diploids and apomictic polyploids are known for almost all of them. |
|
| The results show that early fertilization leads to the formation of apomictic embryos while fertilization at anthesis favours the formation of sexually derived embryos. |
|
| The resulting hybrids often are apomictic and locally distributed. |
|
| Molecular characterization of clonal population structure and biogeography of arctic apomictic Daphnia from Greenland and Iceland. |
|
| The winged, wind dispersed seed of Phaedranassa would facilitate dispersal of apomictic seed away from the maternal plant. |
|
| The invention of apomictic crops is expected to help feed an ever-growing world population and reduce environmental damage. |
|
| Some botanists in the past recognised 1000 or more species, many of which are apomictic microspecies. |
|
| Deciphering the origins of apomictic polyploids in the Cheilanthes yavapensis complex. |
|
|
|
| Utilization of apomictic and dioecious method of reproduction in breeding of Poa sp. |
|
| First, like many other members of the rose family, it is apomictic. |
|
| There are a number of different opinions regarding the validity of some species, notably apomictic microspecies and whether some 'species' may actually be hybrids. |
